The Align TREX 450SE V2 CCPM Kit (Superior Edition), comes with the new 430XL (3700KV) and 35X Electronic Speed Control. This is LATEST V2 450SE Superior Edition with NEW Blue Main Gear and Metal Pulley. This version features the Black Carbon Fiber main frame. T-Rex 450 Superior Edition Version 2 (eCCPM) represents the state of the art in micro helicopter technology, utilizing the latest design techniques and highest material quality, aluminum parts are anodized in a pleasant blue color and carbon assembly. This kit is for the flyers who want uncompromised performance and quality. This SE arrived with 80% pre-assembled. New improvements on the Trex 450SE V2 Superior Edition: New gear ratio(4.24:1), suitable for the motor with higher KV, provides more safety. Uses Aluminium alloy drive pulley and tail drive pulley, high rigid and wear resistance. It is efficient to reduce the rotation loss and makes it more smooth. All kit uses stainless steel linkage ball, wear resistance, anti-oxidization. Tail rotor hub made of stainless steel, very rigid. Features: New CNC carbon frame only 1mm, improved the rigidity and perfect for 3D flying. Changing servo location to CCPM version, new aluminum parts for prompt, precision actions. Battery mounting plate connects to main frame. It makes the center of gravity closer to rotor blade, reduced the correction when the heli rotation rolling. Rigid CNC aluminum rotor head for precision and smooth movements. Using Ball and Hill two systems mixing control. Through simple structure of Ball control system, power-saving of Hill system and CCPM control, can simultaneously control 3 servo for AILE, EVLE, PIT 3 actions. This CCPM control system is great for 3D flying control and extending life cycle of servos. New streamlined carbon tail rotor blades makes the gyro more efficient. New tail rotor control set, CNC control piece and movable ball link for smooth pitch travel. Providing flybar weight - When normal flying, you can add the weights on flybar paddles for stable flight. When aerobatic flying, you don't need to add the weight, but you can see the flexibility of 3D actions. CNC Metal tail unit and tail holder are using high rigid aluminum, falling resistance. Use 32 pcs precision bearing. Use CNC high precise aluminum alloy linkage ball. Great stable and sensitive mixing lever design. Can display the great stability and precision for 3D flight. T-Rex 450 SE special adjustable pitch system, hold rotation system, tail rotor drive belt system. It is a work of great originality for helicopters.
